The present invention will be described in detail below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
A cut-parts packaging structure is shown in figures 2-5 and comprises a bottom layer cloth 4, an elastic layer 3 and a surface layer cloth which are sequentially laminated; the bottom cloth 4 is connected with the elastic layer 3 through a stitching line 5; the surface layer cloth consists of a plurality of connecting parts 11 and a plurality of fold parts 12; the connecting part 11 is connected with the elastic layer 3; a gap is present between the fold 12 and the elastic layer 3. The elastic layer 3 is a rubber band layer.
The adhesive layer is also included; the adhesive layer is positioned between the surface layer cloth and the elastic layer 3; the adhesive layer comprises a plurality of adhesive parts 21; the adhesive part 21 is matched with the connecting part 11 in position; the connecting portion 11 is adhesively connected to the elastic layer 3 through the adhesive portion 21.
In the surface fabric, the connecting part 11 is arranged outside the wrinkle part 12; the outside of the connecting part 11 is the corrugated part 12.
The bottom cloth 4 is connected with the elastic layer 3 by a sewing thread, and the bottom cloth 4 can limit the maximum stretching distance of the elastic layer 3. Avoid the elastic layer 3 to take place too big elastic stretching deformation, lead to the elastic layer 3 fracture. And the elastic layer 3 can be prevented from being excessively stretched and separated from the surface layer cloth.
As shown in fig. 3, when the surface fabric and the elastic layer 3 are connected by the connecting portion 11, the elastic layer is in a stretched state. After the elastic layer is shrunk, as shown in fig. 2, the connection part 11 and the elastic layer 3 are kept connected, so that the connection part 11 is less affected by the shrinkage of the elastic layer 3, and the original state of the connection part can be kept. When the elasticity of the used elastic layer 3 is large and the contraction strength of the elastic layer 3 is large, the connecting part 11 is deformed to a small extent, but the deformation degree of the connecting part 11 is far smaller than that of the folded part 12. However, since a gap is formed between the wrinkle part 12 and the elastic layer 3, the elastic layer 3 tends to bulge outward when it contracts, thereby generating wrinkles.
In a further scheme, the corrugated part 12 is a first strip, and the connecting part 11 is a second strip; the corrugated portions 12 and the connecting portions 11 are alternately arranged.
As shown in fig. 4 to 6, the corrugated portion 12 and the connecting portion 11 are vertically striped. The strip-shaped corrugated part 12 and the strip-shaped connecting part 11 are used for forming vertical strip-shaped spaced corrugations.
In other aspects, the connecting portion is circular, oval, or polygonal. Alternatively, the corrugated portion is circular, elliptical or polygonal. By providing the corrugated portion 12 and the connecting portion 11 in different shapes, the corrugated portion 12 and the connecting portion 11 combine into different textures or bubble effects when the elastic layer 3 contracts.
The connecting part 11 comprises a connecting frame 13, and the connecting frame 13 is positioned at the periphery of the cut-part cable structure. The connecting frame 13 is arranged on the periphery of the cut piece packaging structure, so that the folds on the periphery of the cut pieces are prevented, and the fold appearance of the surface layer cloth is kept.
When the elasticity of the elastic layer is large, as shown in fig. 5, the connection frame 13 is not provided with the folded cloth at intervals, so that the connection frame 13 is wholly contracted to form a plurality of fine wrinkles, but the wrinkles are not transferred to the middle strip-shaped connection part 11, and the connection part 11 is not easy to deform.
As shown in fig. 6, the panel cable structure has a length direction; the bottom layer cloth 4 and the surface layer cloth are connected into a whole at the side surface in the length direction. The two ends of the cutting piece bundling structure in the length direction are connected through a connecting cloth piece 6 to form an annular shape. The connecting cloth piece is preferably made of original cloth and used as a cuff. When in use, the bottom layer cloth 4 is positioned at one side close to the human body, and the surface layer cloth is positioned at one side far away from the human body.
Example 2
A rubberized strip making process for making cuffs comprising the cut strip structure of example 1, comprising the steps of: as shown in figure 6 of the drawings,
s1, preparing cut pieces of cloth; stretching the elastic layer, and sewing and connecting the stretched elastic layer with the bottom cloth; the cloth adopts 20cm long cloth as surface layer cloth and bottom layer cloth. An elastic piece with an original size of 15cm was used as the elastic layer. Stretching the rubber band to 20cm, sewing with bottom cloth, wherein the bottom is Gaoshi PP thread with needle pitch of 10-11 needles per inch, and the PP thread contains rubber band. The two lane lines are positioned at the position of the bisector.
The black and white vertical lines in fig. 6 only indicate the wrinkle structure, and do not indicate that the wrinkle lines of the surface layer fabric and the bottom layer fabric are the same. Typically, the bottom layer of fabric has more folds than the facing layer of fabric.
S2, coating glue on the surface layer cloth, wherein the coating area is the whole surface layer cloth, covering the surface layer cloth on the stretched elastic layer, and the glue is positioned between the surface layer cloth and the elastic layer; selecting a glue pressing template according to the preset shapes of the fold part and the connecting part in the surface layer cloth; and pressing the adhesive to connect the connecting part with the elastic layer. The glue adopted is 301 glue taking alpha-ethyl cyanoacrylate as a main component.
The moulding was performed using a moulding template as shown in figure 7. A hollow part 71 in a vertical bar shape is provided on the frame 7, and the hollow part 71 corresponds to the fold part 12 in the cut piece. The width of the hollowed-out portion 71 in the vertical direction is smaller than the width d of the cut piece. The hollowed-out portion 71 does not cause a pressure-sensitive adhesive treatment to the fabric, and can keep the wrinkle portion 12 from adhering to the elastic layer 3.
Pressing the glue by a glue pressing machine at the temperature of 140 ℃ and 150 ℃ for 15-18s under the pressure of 5-6kg/cm2. Within the above glue pressing parameter range, after the rubber layer with the length of 15cm and the cloth with the length of 20cm are pressed, the wrinkle part 12 and the connecting part 11 can keep a strip shape, and the connecting frame 13 has micro wrinkles, so that the appearance is more attractive.
And S3, connecting the two ends of the cut piece by using the connecting cut piece 6. The connecting cutting pieces 6 are made of original cloth and are in a bean curd block shape.
When it is desired to present a bubble, a molding die as shown in FIG. 8 may be used.
Other textures or bubble shapes can be realized only by replacing the pressure price template.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
